How the move works

  1. 1

    Connect NexDNS

    Connect NexDNS with read-only access (API key (Bearer, nxd_ prefix)).

  2. 2

    Connect Akamai

    Connect Akamai (EdgeGrid API client (host, client token, client secret, access token)). Write access is only used when you apply.

  3. 3

    Review the preview

    Check every record marked Review or Unsupported. Each one explains what changes and why.

  4. 4

    Apply to Akamai

    We snapshot the Akamai zone, write in batches, and leave NexDNS untouched.

  5. 5

    Verify

    We query Akamai's own nameservers for every record and compare the answers before you switch.

  6. 6

    Switch nameservers

    Lower TTLs a day or two ahead, remove any DS record if DNSSEC is on, then point the domain at the new nameservers at your registrar.

Good to know about NexDNS

  • The SOA record and the apex NS records are managed by NexDNS and can't be changed, so dual-hosting a zone with a second provider isn't possible.
  • Records are written one value per request against a per-account rate limit, so large zones take a while to apply.
  • Only A, AAAA, CNAME, MX, TXT, NS, SRV, CAA, PTR, ALIAS, DNAME, DS and TLSA are supported; ALIAS is the way to point the apex at a hostname.

Access we need: zones.read and records.read for the preview; add records.write to apply and zones.write to create zones or switch DNSSEC. API access needs a Pro plan or higher.

Good to know about Akamai

  • AKAMAICDN and non-DUAL AKAMAITLC records point at Akamai edge hostnames. Other providers have no equivalent, so recreate them as CNAME or ALIAS records by hand.
  • Apex ALIAS records are stored as AKAMAITLC records with the DUAL answer type. ALIAS records below the apex become CNAMEs.
  • TXT values can't contain double quotes or backslashes.

Access we need: DNS—Zone Record Management API: READ-ONLY for the preview, READ-WRITE to apply.

Questions

Will there be downtime moving from NexDNS to Akamai?

Not if both providers serve the same answers during the switch. The records are copied to Akamai and verified before you change nameservers, so resolvers get the same answer from either side while caches expire.

Do I have to delete anything at NexDNS?

No. We never write to NexDNS. Keep the old zone for a week after cutover so you can switch back instantly if anything looks wrong.

What about DNSSEC?

If DNSSEC is on, remove the DS record at your registrar and wait for it to expire before switching nameservers. Then enable DNSSEC at Akamai and publish its new DS record. The cutover plan walks you through each step.
